Product overview
The MDOT COMMS A43-1400 provides video and data transmission through a single-band TDD radio link. Its 2T2R RF configuration operates at 1335–1475 MHz with 43 dBm (20 W) transmit power, with customization available for both the operating band and transmit power. Networking options include point-to-point, star and mesh, alongside spectrum monitoring and smart frequency selection. Communication distance is approximately 200 km under ideal line-of-sight conditions. The radio offers 10 / 20 MHz channel bandwidth and BPSK, QPSK, 16QAM and 64QAM modulation, with AES encryption.
Physical integration requires space for a 180 × 80 × 30 mm unit weighing 500 g. Its connection layout comprises two SMA RF ports, one power interface, two Ethernet interfaces, two TTL/RS232 interfaces and one SBUS/TTL interface. The supply requirement is DC 24–30 V, with a typical specification of 28 V at 3 A; power draw is ≤85 W. The temperature range is -40 °C to +75 °C. Maximum throughput is greater than 20 Mbps, while latency is ≤10 ms.
